MACHINE FOR CUTTING AND PASTING PAPER.

Specification of Letters Patent.

Patented Dec. 11, 1906.

To all whom, it may concern:

Be it known that we, JOHN S. HUGHES, residing at Hudson, county of Columbia, and CHARLES J. PRANKARD, residing at Troy, county of Rensselaer, State of New York, citi- Zens of the United States, have invented certain new and useful Improvements in Machines for Cutting and Pasting Paper, of which the following isa specification.

The invention relates to such improvements and it consists of the novel construction and combinationof parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings, and the letters of reference marked thereon, which form a part of this specification.

Similar letters refer to similar parts in the several figures therein.

Figure 1 of the drawings is a view in side elevation of our improved machine. Fig. 2 is a view infront elevation of the same. Fig. 3 is a horizontal section taken centrally through the cutter-roll and longitudinal cutter-on the broken line 3 3 in Fig. 1. Fig. 4 is a vertical section taken centrally through the paste-wheel on the broken line 4 4 in Fig' 1. Fig. 5 is a vertical section taken centrally through the draft rolls on the broken line 5 5 in Fig. 1. Fig. 6 is a vertical section taken on the broken line 6 6 in Fig. 2 through the transverse knives and the grooved portions of the draft-rolls and bed.

, The object of our invention is to provide mechanism for automatically dividing a web of paper into small sheets and delivering the sheets with one or more edges pasted.

A is the frame of our improved machine, from which are erected the standards B, containing bearings for the paper-roll support; the standards C, containing bearings for the cutter-roll C the standard O containing bearings for the longitudinal cutter I groove G, into which the paper is foroedby the sharp edge of the rotary cutter C whereby the web is divided along its longitudinal middle as it is drawn between the cutter and cutter roll by the rotation of the draftrolls D.

Intermediately of the draft-rolls and cutter-roll is located the paste-wheel F, mounted upon the shaft F, rotary in bearings on the walls of the paste-reservoir F The paste-reservoir is attached to the machine-frame, and the paste-wheel issupported with the lower portion of its periphery within the reservoir and immersed in the paste contained therein, while its upper portionproj ects above the reservoir into the path along which the cut edges of the web of paper travel.

The cut edges of the paper lie closely together at the middle of the web, and in'passing over the paste wheel as the web is drawn along by the draft-rolls the paper is supplied with a coating of paste along the cut edges. The outer portions of the web are supported during the pasting operation by the drums F on either side of the pastewheel. After the paste has been thus a plied to the out edges along the middle oft e web the paper passes under a tension-rod T to the draft-rolls. The tension-rod is vertically adjustable in the frame of the machine, whereby the tension upon the paper may be varied. The draft-rolls are constructed with a middle peripheral groove D adapted to receive the cut and pasted edges of the web as the paper is drawn along by the engagement therewith of the ungrooved surfaces of the rolls. The grooves D prevent the asted portions of the paper from being broug t into contact with the surfaces of the rolls to soil the same. As the draft-rolls are rotated the longitudinally out and pasted web is forced out from between the draftrolls upon a delivery-table, which may be of any known form.

e have shown in the drawings a preferred form of table especially adapted for the delivery of thin paper and comprising a rectangular frame G, supported upon the frame of the machine at G and provided with a convexed top formed of a plurality of bowed rods extending longitudinally of the frame.

grooves in the draft-rolls.

The frame is adjustable upon its support, whereby the inclination of the frame can be varied.

Intermediately of the delivery-table and draft-rolls is a supporting-bed H for the paper and mechanism for cutting the Web of paper transversely, comprising a horizontal knife K, fixed just above the bed H, and a vertically-movable knife E, adapted .to cooperate with the fixed knife to cut the paper. The bed H, adjacent to which is the pasted surface of the paper, is provided with a groove H, similar in form and function to the The knife E is vertically-movable in slideways in the standards E to and from the fixed knife K.

As a means for operating the draft-rolls and knife E we have shown a power-shaft S, provided with fixed and loose pulleys S and S adapted to receive the driving-belt S which shaft is connected with a countershaft S by the belt S and pulleys S and S The shaft S is provided with a pinion S -which meshes with a gear S on the crankshaft P. A crank P on the inner end of the crank-shaft is connected by the pitman P with the movable knife E, whereby the rotary movements of the crank-shaft impart to the knife vertically-reciprocating movements in its slideways. The other end of the crankshaft is provided with a crank-arm P upon the wrist-pin P of which is pivoted the lower end of the rack P The upper end of the rack is movable in a box or slideway P pivoted at P and is provided with teeth adapted to mesh with a pinion P fixed upon the shaft P The ratchet-Wheel P is also fixed upon the shaft P and rotates therewith and with the pinion P The gear-wheel P is rotary upon the shaft P and meshes with a pinion D on the spindle of one of the draftrolls. The draft-rolls are connected by gears D. A pawl D connects the gear P with the ratchet, whereby the gear is operated by the rotary movements of the ratchet in one direction only.

The operation of the driving mechanism is as follows: The crank-shaft having a constant rotary movement imparts to the knife E, as well as to the rack P, vertically-reciprocating movements, by means of which the knife is brought into and out of cooperation with the fixed knife and the rack is caused to slide up and down in its slideway-box, thereby rotating the pinion P and ratchet first in one direction and then in the opposite direction. The rotary movement imparted to the pinion and ratchet by the upward movement of the rack is in a direction to cause the gear P to be rotated by means of the pawl D and to thereby operate the draft-rolls to feed the paper out upon the delivery-table. The movement imparted to the pinion and ratchet by a downward movement of the rack is in a direction to cause the pawl to slip over the ratchet-teeth without operating the gear P The cranks are so fixed on the crank-shaft that the idle period of the gear P and the draft-rolls is simultaneous with the period of cooperation of the knives. The length of the sheet of paper delivered. to the table between each two successive operations of the knives is determined by the throw of the crank P As a means for varying the throw of said crank to adapt the machine for the delivery of larger or smaller sheets We attach the wrist-pin P to a slide-nut N, movable in a longitudinal slideway in the crank-arm and adapted to be operated by a screw N, passing through the nut. By rotating the screw the nut and wrist-pin can be moved along the slideway toward or from the center of the crank-shaft, thereby changing the effective length of the crank-arm.

The longitudinal and transverse cutters may be of any known form.

\Nhat We claim as new, and desire to secure verse cutting mechanism, and in line with the longitudinal cut edges of the web and a pair of draft-rolls having a peripheral groove in the path of the pasted portions of the web.
